Sell Diamonds — Questions & Answers
- Who buys diamonds in Houston?
- Gold King at 6809 Southwest Freeway buys loose and mounted diamonds in Houston, grades stones in front of the seller, and pays cash the same day. Call 713-997-0875.
- Do I need a GIA certificate to sell a diamond?
- No. A GIA or AGS report helps confirm grading and can support a higher offer, but Gold King grades stones in-house at no charge.

- We test every stone and will tell you if it is lab-grown or moissanite. Lab-grown diamonds have a much lower resale value than natural stones, and we quote accordingly.
